Customer ratings & reviews

My mouth is on the small side. I was worried the guard wouldn't work for my small mouth. I contacted customer service and they said to just request smaller trays for the impression process. One of the tray sizes was perfect. I absolutely recommend this product. Aside from the guard fitting perfectly and serving its purpose, the customer service team is the real gem. They are responsive and very knowledgeable. 5 Stars

Better quality than what I got at my dental office. I would definitely recommend Sentinel Mouthguards to family and friends. I am very pleased with the fit of the product and customer service.

Great quality and great company! I was so happy when my retainers finally arrived to my door! I wasn't sure if my impressions were going to be good enough so I emailed a couple of pictures of the impressions and they said it was best to send new impression kits to me to retake them. I got it right the second time and received my retainers yesterday! The fit is perfect. Thank you!

I've played Hockey since I was little and have always hated buying mouth guards. They;re uncomfortable and I get yelled at for not having it hang out of my mouth. This is the first guard that has actually fit correctly. There is nothing that comes close to this fit and it's impossible to have this one hang out of my mouth because I have to physically remove it by popping it off of my back teeth. No comparison. 5 stars and highly recommended!

I am not the type to write reviews but this product is outstanding and really works as advertised. Highly recommend to anyone who needs to keep their teeth straight after braces but not willing to pay the dentist' price! Will be buying again if needed.

I couldn't find a night guard lab locally, so I purchased this one online & I'm so glad I did. I use this product daily and nightly. The material is soft, clear and unnoticeable. I went with the lower teeth guard. Impression process was easy. I made a nice mold of my teeth. The guard itself is sleek, slim and not too tight. Once I use this one up, I'll definitely purchase this night guard again.

I wanted to write this review because my experience has exceeded my expectations. I have been wearing my dental retainers for 9 months and I also grind my teeth at night and ended up doing some damage to the retainers. I contacted Sentinel and they asked me to upload a picture to their email of the wear on the retainer. They still had my impressions on file and made me new dental retainers because I was still within my 1 year warranty. I don't know of any other dental office or lab that would do that. They paid for the shipping and everything. I am impressed with the level of quality of the product, the customer service and the willingness to back up the warranty. Impressive and refreshing company.

I spent over $500 from my FSA account to have my final custom dental retainers made by my dentist. They fit perfectly, but apparently I grind my teeth too and had to get them replaced. There was no option from the dental office given except to order another set for $500. Umm... no! After reading the rave reviews for the Sentinel Mouthguards on Amazon, I decided to give them a try. I must say that I am extremely pleased and highly recommend them. The directions were easy to follow, I created a great fit myself. Not to mention that it saves me $360! I’m never bothering to order another set of retainers from the dental office. Literally saved me hundreds. Thank you!!

I got this for my elderly mother because she grinds her teeth VERY badly at night. Her mouth is tiny, and since the process requires taking a teeth impression, I asked for extra material. Getting the teeth impression on her tiny mouth was a little difficult but only because again, small mouth. It molds and hardens very quickly. in a matter of 2 minutes, so it may take a couple of tries to get it perfect, but overall it's easy to use, and has easy directions. She says the mouth guard fits her well. A good purchase for the money in my opinion.

Excellent service!
